sustainability stories. this week, is it a boat or a plane? i am on board the ferry that can fly! why has nobody made an electric hydrofoil, flying ferry before? i think the main reason is it is freaking hard! we are in india where solar dryers are battling food waste. and an eye in the sky on energy use. nice outfit by the way. thank you. i'm taking the world temperature to assess climate action.
1:32 pm
stockholm, capital of sweden and the city of islands, 14 of them to be precise, which makes water transport a big thing around these parts. so today i have decided to take the ferry. but this is no ordinary ferry. because this ferry can fly! this is the candela p—i2, the prototype of a ferry which should go into service injuly 2024 and its cruising speed of 25 knots and wings called hydrofoils provide huge amounts of lift in the same way that aircraft wings can get a plane off the ground, these wings can raise the whole hull
1:33 pm
above the surface. i've started to notice more and more boats and even windsurfing and kite surfing having these foils underneath the board so the entire thing can lift out of the water. because hardly any of the boat is having to push through the water, it does not need as powerful a motorcar. it does not need as powerful a motor. that means there is something else that is very special about this craft. it is electric. these small propellers are all that are needed to get the ferry up to speed and its on—board batteries give it a range of 50 nautical miles, all of which promises to make waterborne transport a whole lot cleaner and a whole lot greener. normal boats consume an awful lot of fuel and are extremely inefficient compared to land—based transport.
1:34 pm
because the boat is trying to push its wake through the water and much resistance? a lot of resistance and you can use batteries on ferries if they run very slowly, but if you want to go a bit faster and longer, the whole thing collapses because you could of course put in more batteries, but at the end, you are putting in so many batteries, the boat will sink. it will sink. you have a fiscal limit that you can't get around. he says that one hour of charging will allow this ferry to run for three hours, meaning a good service during the morning rush and one charge to be ready for the afternoon peak after being recharged at lunchtime. another advantage to being almost entirely out of the water as well, it does not bounce about on the waves! it is pretty steady. i can't really tell i am out of the water but i can tell i can feel the waves around but actually it is using the same
1:35 pm
hydrofoil technologies that you can see it is out of the water which means... and look at him — he's having the time of life out there! but whereas the speedboat is built for pleasure, leisure and basically showing off, the ferry is being pitched as a way of making waterborne public transport competitive in fuel costs and environmental costs as well because, as well as not feeling the waves, it does not make them, either, meaning it's good for everything that lives here. traditional ferries create big wakes and when it drives in our sensitive archipelago it is a sensitive ecosystem with marine life and the birds and the fish, it
1:36 pm
causes erosion from the shorelines. that is a really big challenge for us. we need to reduce the wakes to be able to drive in a more sustainable way in our sensitive environment. the principle of hydrofoiling is not that new but it has only been recently possible to do in this way. the first reason is that we now have materials that are up to the job. you need thin blades, made super strong but very thin to not create too much drag. typically they use carbon fibre, a perfect material and you can build them in fairly small volumes, otherwise you would have to rely on steel, it becomes heavy and costly to manufacture. the second reason is the high—end computation going on below deck. this is the science bit. when you raise a boat almost entirely out of the water, it becomes unstable because you have all the weight up here above the wings that it is balancing on in the water, a bit like trying to balance a pencil on your finger.
1:37 pm
in order to keep it upright you have to do a lot of this and that is what this boat is having to do. having to adjust its position hundreds of times a second to keep it perfectly balanced. you could not do that manually so this thing is covered in sensors that monitor exactly what the orientation is and the computers are doing the compensation and they do that by adjusting the angle of the wings in the water. again, hundreds of times a second, to keep a perfectly balanced. to keep a perfectly balance. it is the same reason why drones are able to stay stable in the air and on these early test flights, christian is able to tweak and experiment with the boat's behaviour by changing the settings live on his laptop. we are turning... one of the things you can do when you are precisely controlling the orientation of the boat all the time is you can artificially bank like this when you are turning which is more comfortable for the passengers. because if the boat was to remain level, everybody would be pushed to one side so the banking is artificial.
1:38 pm
there is a limit to the size of the swell this type of craft can cope with but in inland waterways this technology may very well soon be making waves, by not making waves...! although like a lot of modern life, the smooth ride will depend on the computers and sensors doing theirjobs at all times, which is no mean feat. why has nobody made an electric hydrofoil flying ferry before? i think the main reason is it is very hard! over 70 countries have commitments to net—zero targets. some are enshrined in law, others are goals laid out in policy. large companies have also made net zero pledges but how do we know
1:39 pm
that they are being met? there is one company that might have the answer. satellites have been capturing images from space, for decades. this is a radar one here and you also have optical images like these, any cloud cover around you will not see what is going on beneath and you need daylight for most of these. but satellite vu has a different plan, for them, it is about thermal imaging. its first satellite was launched injune on the spacex rocket flying out of california. it started sending back high—resolution images to earth, its thermal sensors enabling it to chase hot and cold features down to 3.5 metre accuracy.
1:40 pm
that cycle, there is a lot more than four kilometres. it is the culmination of years of work. we have satellite vu, the world's thermometer and these are literally the raw images. here, the first image we took was of rome and you can see the hot areas in brighter colours and the blue areas are the cooler areas in the city. this one is taken at night and what you can see, the vatican, is very, very hot. this summer, there were big heatwaves, that building absorbed a lot of energy and at night it is radiating. the heat which are still images in short images and videos could have wide application but particularly useful in climate related matters.
1:41 pm
we think every city would want this, new city managers called chief heat offices, seven appointed around the world and one is in athens for example. and they are wanting this data so they can go and help people keep the city cooler to keep the stress on people less and save energy. but the bigger picture is to help monitor how companies are meeting their net zero commitments. you can look at oil storage, for example and see how much fossil fuels are being burnt and how much are being pumped. when people are declaring net zero or reducing their oil consumption, we can come and verify that that is actually occurring. 60 organisations are currently playing around with these early heat map images to see if they can improve their existing climate models. hot sat one was assembled by
1:42 pm
satellite technology in guildford. you get one shot at launching something like this, how stressful is the process? pretty stressful! i think it is a high intensity business. especially projects like this that are very short schedule but it is very exciting when it does launch. seven more satellites will be joining hot sat one over the next few months. the aim is to increase the amount of data being collected, identifying temperature profiles of individual buildings, offices and factories. if we're striving to help the planet, if we're striving to get to net zero, you need this transparency of information. and we've done it. time for a look at this week's tech news. openai co—founder sam altman is returning to the company days after he was ousted. mr altman's sacking astonished
1:43 pm
many and led to staff threatening mass resignations until he was reinstated. the battle at the top of openai began when the original board decided to remove mr altman, saying they had lost confidence in his leadership. binance chief executive changpeng zhao has resigned after pleading guilty to money laundering violations. the usjustice department said the world's biggest cryptocurrency exchange had helped users bypass sanctions. it's ordered the firm to pay for your $5 billion in penalties and forfeitures. mr zhao said he made mistakes and stepping down was the best move for the company. scientists in scotland are using robotic sub—sea gliders to check a system of ocean currents for signs of climate change. they're monitoring the conveyor belt which regulates global temperatures by carrying warm and cool air around the world. there is some concern the system is weakening.
1:44 pm
these gliders really help us go to places we would not really get to in the winter and they can stay out for months at a time whereas on a ship you're kind of time—limited. food wastage is a huge problem across the globe and in india this is compounded by the fact that cold storage facilities can be few and far between. but one of this year's earthshot prize winners is a start—up working on a solution. nikhil inander went to find out more. here's a shocking statistic. more than a third of all fruit and vegetables grown in india end up in landfill like these. but across some 400 villages in the western part of the country, these solar powered dryers, all operated by women, are now tackling the challenge head—on.
1:45 pm
these are built by sas technologies, a start—up that won the prestigious earthshot prize for climate impact this year. this isn't exactly a high—tech device at all with any complex technology, electronics or chips but these dryers expand the life—cycle of basic perishables like onions for instance or tomatoes that would otherwise have rotted. it's a frugal, low cost, climate friendly solution to preserving second rate produce that normally does not find a market. they're also a cheap alternative to expensive cold storage facilities, which are few and far between in these rural areas. solar drying is known since ages as the open sun drying. shital somani is one of the co—founders of the start—up that makes these dryers. shital, can you explain exactly how this works? in the solar drier, basically we use the solar energy to convert
1:46 pm
in the heat form and give that heat to the product. when we say about the heat, the heat is from this surface, which is a full grade insulator black metallic surface, it is giving the heat from the bottom to the product and at the same time, when the air enters from this aspect, we close the drier, the air also carries the moisture from the driver and carries the solar radiation which is falling from this top surface on the product. and all three forms of heat transfer helps to remove the moisture from the product. keeping the tech simple and low cost has allowed sas to on—board thousands of women entrepreneurs to do thisjob. it's been a game changer for the localfarmers. at the crack of dawn, shivagi is sorting his onion harvest to be sent to the drying facility. translation: onion prices are very volatile. _ when the cost of transport is more than the cost of production, i used to just throw away the crop.
1:47 pm
many times, the lower grade crop would not get sold, nearly half of what i had grown would rot. now, all of it gets picked up at the farm gate and my income has gone up substantially. once dried, the produce comes to this factory, which processes it further into packaged food that is sold to big companies and restaurants. the farm—to—factory chain gives growers an assured market and helps cut middle men. can you talk a little bit about about the various levels you are creating impact? we are creating impact at the three main levels. first is the food wastage where we are reducing the food wastage by converting this b or c grade material into the value added products — that is the first claim. we are giving these dryers, most of the dryers is 100% are used by the women entrepreneurs, the women farmers. and the third is the carbon emissions as this is the solar best technology so we are reducing on the carbon emissions also. right now, we are 2000 women
1:48 pm
farmers, three years�* time we could teach 10,000 women farmers. the farmers network that we are building, which is a direct or indirect farmers network, we can see clearly one million farmers�* lives we can impact. india is vast and diverse. identifying the right produce in the right geography and creating a market for it is a challenge. but solutions like these, if scaled up, can help millions of india's poorest farmers reduce waste and grow their incomes. in the race to reduce emissions, plans to build wind farms are skyrocketing. but while the electricity that they generate is clean, the green industry has a waste problem, and now, the race is on to try and solve that, as adrian murray has been finding out.
1:49 pm
these towering machines are getting ever more powerful. nowhere is that more on show than at this test centre in northern denmark. it is the latest and biggest turbines that they have, the prototypes. this is like seeing them testing the future right here. the largest a staggering 208 metres high has broken world records for the most power. and experts say they're only getting bigger. this race towards bigger and bigger turbines will continue for a while more. we are looking into the possibility of creating a new test centre in denmark and the design turbine we are designing for is a50 metres from ground to highest tip. by 2030, wind power could supply a fifth of the world's electricity. we need clean energy, but this green industry has
1:50 pm
a growing headache when it comes to waste. turbines are built to withstand the forces of nature, they're flexible, light and superstring. flexible, light and super strong. but that's also where the problem lies. when they reach the end of life, they're really hard to recycle. while the steel in the towers can be reused, the massive blades are almost indestructible. and as older models are replaced, many get dumped in landfill. by 2050, there could be 43 million tonnes of redundant blades globally that need to be dealt with. it is problematic because we want the renewable energy to be truly sustainable, and if you have a waste material that goes to land filling, it's not truly sustainable. it's a problem players have been scrambling to figure out. and we might now have some answers.
1:51 pm
there have been creative ways of reusing wind turbine blades, like this bike shed. they've even been repurposed for playgrounds, bridges and building cladding. but this won't really tackle the growing volumes. one immediate solution is to chop up and finely shred them. it's burned as fuel and used as an ingredient for cement production. this us plant has already handled more than 3,500 unwanted blades. now, turbine makers siemens gamesa have had a breakthrough of its own. it manufactures some of the world's biggest blades at its site here. and while this one looks like any other, it can be recycled. it all comes down to a resin called epoxy, which acts like a really
1:52 pm
strong superglue binding together the fibreglass. usually this is incredibly tough to break down. but not here. we change something in the backbone of the chemistry. this has actually gone through our recycling process. we just turn it around. here, you can see all the different glass layers placed through in the production of the blade and how they are separating from the blade. to do that, it needs to be soaked in a big bath of mild acetic acid. after a few hours at 80 celsius, then you get the result you see here. so it's just like vinegar in a supermarket? exactly — just like you would make pickles or descale your coffee pot. i can actually smell that. there is a scent of vinegar coming from the blade. this won't tackle today's waste, but when these blades retire, the materials could go into making other things.
1:53 pm
it could be furniture, suitcases, you can use it for surfboard manufacture, so general consumer goods. but not. . . new turbines? not as it is right now, but i'm never going to say never. so far, only a small number have been installed, but they'll soon be used for bigger offshore projects here in europe. at this research lab, scientists are taking a different approach. this was a part of a wind turbine that was decommissioned. basically, put the tip in there and you add a catalyst. they have discovered a chemical process that gently breaks apart the components. precise details are still under wraps, but it turns out it's relatively simple. these are the glass fibres which have kind of come apart a little bit. yes, i can see those.
1:54 pm
because they are not bound together any more. you can see it's very clearly separated into its different components. that means the fibres and even that type epoxy resin could be recovered and potentially reused. this has been quite remarkable. we thought that these materials were extremely strong and indestructible. now, we've found the chemical processing that can chew its way through the epoxy. and, in theory, it could work on all kinds of turbine blades already out there. what we find exciting is we are sort of the first to be able to do that. there are potentials in recycling such tough materials, not only confined to the wind turbine industry, there is the aeronautic industry, space industry, cars. this technology still needs to make the leap from a test tube to the real world. but with new solutions on the table, perhaps this growing waste problem could be headed off before it gets too big. and that's it for our round—up of some of the latest sustainability stories. hope you've enjoyed them.
1:55 pm
from sweden and from me and my electric ferry, thanks for watching. and...i wonder what this does? hello there. we've had a rather cold and frosty start to sunday morning. temperatures down to minus five degrees in parts of northern england and southern scotland. but for many of us, it's been a fine start with some clear skies, a bit of sunshine out there, but also one or two fog patches which may be slow to clear in parts of northern ireland and central scotland. but for the rest of today, for most of us, it's a case of sunny spells. now, the reason for the change in the weather from the recent stormy conditions is this big area of high pressure which becomes established across the uk today and indeed over the next few days. so it keeps things mostly dry.
1:56 pm
and i say "mostly" because there are one or two showers coming in across the north—east of england falling as snow or some wintriness over the higher ground, a few showers also in the south—east of england this afternoon. but elsewhere, dry with some sunny spells, maximum temperatures getting up to about two to six degrees celsius. but there could be some stubborn fog across some parts of scotland and northern ireland, which will reform again as we go through tonight. it's the northern half of the uk most at risk, but there could be one or two fog patches even further south. a few showers still coming in across eastern areas. but the main thing about tonight really is how cold it's going to be. once again, temperatures widely below freezing, minus five celsius for northern parts of england and across scotland. we're beneath this area of high pressure where the cold air is sitting beneath that. and these white lines here across southern areas of england, indicative of some fairly brisk winds, which will bring in some wintry showers on monday morning. so if you're travelling, be aware of the fact that we could see some sleet and even some snow, even a hug over
1:57 pm
that we could see some sleet and even some snow, even over higher ground could be settling snow for a time on monday in the south east of england. there'll be a few showers coming in across the north—east of england. but on the whole, once again, it's going to be a dry day for most of us on monday. any mist and fog should tend to clear away. one or two may linger on into the afternoon. on the face of it, temperatures will be about three to five degrees celsius. but factor in that rather chilly east or north—easterly wind, it will feel more like freezing across many parts. and for the rest of the week, little change really. it's going to stay dry for most of us. there will be some sunny spells, but watch out for overnight frost and some fog, especially during the mornings. and that's the outlook really you can see dry for most of us and temperatures at orjust below the average for the time of year. bye— bye.

live from london. this is bbc news the us secretary of state meets middle eastern leaders jordan's king abdullah warns him of the "catastrophic repercussions" of israel's campaign in gaza. rishi sunak confirms
2:00 pm
that the government is looking at legal options to exonerate sub—postmasters who've been wrongfully convicted of fraud because of a faulty computer accounting system. polls close in bangladesh's election — early indications suggest a low turnout of voters, and the current prime minister is expected to win a fourth consecutive term. and hollywood rolls out the red carpet for one of its biggest nights, the golden globe awards. hello. i'm lauren taylor. jordan's king abdullah has warned the us secretary of state antony blinken of �*catastrophic repercussions�* from the continuation of israel�*s military campaign in gaza. mr blinken is on a tour of the middle east as the us tried to prevent the conflict in gaza from spreading. earlier he met thejordanian foreign minister. king abdullah also urged blinken to put pressure on israel to agree to an immediate ceasefire. next the secretary of state will head to qatar for talks with the emir.
